I disagree. git-version-gen does not have the requirement that a file
.tarball-version does exist. git-version-gen has the requirement that the
first argument that you pass it must exist. (gnulib-tool itself for example
passes /dev/null.)

GNUmakefile passes the argument $(srcdir)/.tarball-version to git-version-gen
without testing whether this file exists or not. This is the bug IMO.
